// $Log: not supported by cvs2svn $
// Revision 1.24  2004/11/25 08:30:58  rurban
// dont extract args
//
// Revision 1.23  2004/11/23 15:17:19  rurban
// better support for case_exact search (not caseexact for consistency),
// plugin args simplification:
//   handle and explode exclude and pages argument in WikiPlugin::getArgs
//     and exclude in advance (at the sql level if possible)
//   handle sortby and limit from request override in WikiPlugin::getArgs
// ListSubpages: renamed pages to maxpages
//
// Revision 1.22  2004/11/23 13:35:49  rurban
// add case_exact search
//
// Revision 1.21  2004/02/17 12:11:36  rurban
// added missing 4th basepage arg at plugin->run() to almost all plugins. This caused no harm so far, because it was silently dropped on normal usage. However on plugin internal ->run invocations it failed. (InterWikiSearch, IncludeSiteMap, ...)
//
// Revision 1.20  2003/11/02 20:42:35  carstenklapp
// Allow for easy page creation when search returns no matches.
// Based on cuthbertcat's patch, SF#655090 2002-12-17.
//
// Revision 1.19  2003/03/07 02:50:16  dairiki
// Fixes for new javascript redirect.
//
// Revision 1.18  2003/02/21 04:16:51  dairiki
// Don't NORETURN from redirect.
//
// Revision 1.17  2003/01/18 22:08:01  carstenklapp
// Code cleanup:
// Reformatting & tabs to spaces;
// Added copyleft, getVersion, getDescription, rcs_id.
//

// Local Variables:
// mode: php
// tab-width: 8
// c-basic-offset: 4
// c-hanging-comment-ender-p: nil
// indent-tabs-mode: nil
